Hi, If you are using P.otel to do your simulation the 555 circuit is already built in to the package, find the Timer.lib which is in the simulation parts library. They slightly modified one of the repolarizing processes to make a plateau potential, similar to that found in a ventricle cell. If temperature goes beyond a particular level (50 Degree in this circuit) then Red LED will glow automatically, otherwise yellow LED remains on below that particular temperature.

The FitzHugh-Nagumo scheme replaces the fast Na current of the HH model with a simplified fast, depolarizing, activation process, and replaces the slow Na inactivation and slow, repolarizing, K current by a single slow inactivation process. Below is the module circuit and an example of its use. In the simulation, the oscillator can enter a metastable state for a long time until numerical error starts the oscillation. Model nonlinear biochem reactions using opamps. I used it to build model neurons, Delta-Notch signaling system, and gene control circuits.
